IMPROVED DEVICE FOR STOPPING BOTTLES, 81,0.

Specification forming part of Letttrs Patent No. 410,292, dated October 13, 1863.

' To @ZZ w/'wm it may concern:

other Vessels 5 and I, the said NATHAN THOMP- sON, do hereby declare the nature of t-he said invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement thereof-that is to say: e

According to my invention for stopping bottles, jars, and other vessels the neck ofthe vessel is made with a groove (or it may be aprojecting ring) around ita short distance below the mouth; and the stopping apparatus (no part of which is permanently attached to the vessel) consists of a ring of sheet metal with flanges projecting inward from its upper and lower edges. This ring is divided intotwo parts, each of a semicircular form, which are hinged together on one side. To the upper flange of one otl the halfrings a circular plate of the same diameter as the interior of the ring is soldered or attached, and in the center of this plate is a hole, and immediately below it a screw-nut is xed. This receives a short screw, to the lower end of which a plate is connected, in such a manner, however, that the screw can turn independently of the plate. A disk or packing of cork or similar material is attached to the plate, and the top of the screw is made with a recess to receive a key, by which it may be turned. Vhen the stopping apparatus is placed on the neek of the vessel and the two half-rings closed together, the ange at the lower edge ot' the ring enters the groove in the neck of the vessel all round at the same time. The plate at the lower end of the screw comes immediately over the mouth of the vessel, and the upper iiange of the part of the ring which is not attached to the top plate comes over the edge of the plate, so as to hold it down to the neck of the vessel. Then by turning the screw the plate at its lower end with the packing upon it is forced down onto the top of the neck, and so closes fluid-tight the mouth of the vessel.

Figure A is a side view of the upper part of the neck of a bottle, together with stopping apparatus arranged as above described, the stopping apparatus being placed on the neck of the bottle, but not lclosed thereon. Fig. B is a plan of the stopping apparatus as it appears when open. Figs. C and D are side views of the same as it appears when closed. Fig. E is a plan of the same, and Fig. F is a vertical section of the stopping apparatus, togetlierjvith a small portion -ot' the neck of the bottle.

In these figures, c is the neck of the bottle, and a the groove therein; b and b', the two parts of the divided ring. These parts have on 'their upper and lower edges flanges projeeting inward, as before mentioned. These parts are hinged together at bf.

c is a circular plate, which is raised or arched up in the center. This plat-e is soldered to the upper part, Z1, of the divided ring.

d is a screw-nut soldered to the plate c at the center thereof, and immediately beneath a hole therein. cis a screw working in this screw-nut, and having a square recess or socket, e', at its center. i

f is a plate riveted to the lower end of the screw e, but so that it can turn freely thereon. This plate is raised in the center, so that the end of the screw c may not come in contact with the thin plate ofv tin plate g. This plate covers the bottom of the plate f, and is turned up around its edges, so as to secure it.

h is a packing-pieee, by preference of cork. It is cemented with shellac or other cement to vthe plate g.

Figs.` G show the key, which is employed for turning the screw e to force the cork h against the top of the neck ot' the bottle. Vhen the cork is thus forced down, the parts of the ring b cannot be opened out to remove the stopping apparatus, but after slackening the screw this, may readily be done.

Fig. H is a side view of a bottle and stopping apparatus of a slightly different construction, and Fig. I is a similar view, but with the stopping apparatus in section. This apparatus differs from that just described in I closed together7 enter u groove in (or under L that the recess c in the top of the screw c is ring on) the neek or around the mouth of the dispensed with, and a head, @2, is substituted bottle or vessel, and also come over the edge therefor, which can be turned by the fingers of the cap, so as to Confine the same7 substituwithout a key. tially as herein described.
